YouTube Fullscreen Stutter Windows 10 Firefox FIX 144Hz +

After trying to hook up HDMI I found smooth performance.However when trying to hook up Display port or DVI i found this relentless stuttering in YouTube.That is the subject of this post.

How to fix it.

Uninstall Your current Flash player.It is clearly corrupted.This issue stems from other versions as well including 64bit Firefox.Both show the same result.Uninstall it.You can try reinstalling it later.If it stutters again.Please report this issue to Adobe.com.
